One interesting … WebTSH then stimulates the thyroid gland to secrete thyroid hormones, Thyroxine (T 4) and T 3. Proper levels of thyroid hormones in the blood are regulated by a classic negative feedback system. If thyroxine and T 3 levels are high, they feed back on the hypothalamus and the pituitary to decrease TSH release.

Web26 feb. 2024 · By controlling how much energy our cells use, thyroid hormones also help to regulate our body temperature. Heat is released when energy is used, increasing our body temperature. Thyroid hormones also play a role in making proteins, the building blocks of the body's cells. They also increase the use of the body's fat and glucose stores. TSH (with a half-life of about an hour) stimulates the thyroid gland to secrete the hormone thyroxine (T4), which has only a slight effect on metabolism. T4 is converted to triiodothyronine (T3), which is the active hormone that stimulates metabolism. About 80% of this conversion is in the liver and other organs, and 20% in the thyroid itself.
